Extend the Gravity-Forms AddOn-Framework with a file-upload field -- 3

I need the possibility to use a file-upload field with the gravity-forms addon-framework. Informations about the framework and a sample plugin you'll find here : [login to view URL] And here : [login to view URL] Another Sample you'll find here : [login to view URL] As you can read at the 'Settings API' section of the documentation, there are a lot of supported field-types, but unfortunality no file-upload. You have to write some code so i can use a file upload field with any new addon that i need to create. So it would be possible to use a file-upload at the form_settings and plugin_settings functions using the wordpress media-upload and gallery. You have to work on your own server and need a copy of gravity forms. You don't have to change the core gravity-forms source code. !! I don't want a file-upload field at the form-editor !!
